It is more of an offer than a request. I am a player (not a creator or anything) of an old strategy game called Visual-Utopia. What I would like to offer you is a map competition for that game. You could draw a map and if administration and community agrees it would be used for playing. It has been a long time since the map was updated, but recently game creator decided that every era (match) map would change. This is a great opportunity to implement a few new maps and maybe change game development course (it is an old game, but has been changed a lot). Your mapping skills might serve a nice purpose here and might be an opportunity to realize yourselves. :)

Check the game out to be more sure what I am talking about.

Some mapping guidelines:

Only mountains, rivers (with bridges), lakes, forests and fields.
Should be recurrent so it could be repeated in x and y axis.
No islands. All land should be reachable.
Some passages should be small so it could be blocked with a blocker town (see example, screenshots)
2500x2500 pixels exactly

The map needs to be repeatable! So if you put two maps beside each others it needs to have a smooth transition over the edges. No cut rivers etc.

Terrain
The map needs to have mountains, water, trees and rivers.

Mountains: 80x80px or 40x40px

Water: 80x80px or 40x40px

Tree: 80x80px or 40x40px

River: 20x20px

These are guidelines, although, it's very important that the terrain is not smaller then 40x40px. And a river is not smaller then 20x20px.

The rivers can have a round shape, but the other terrain should be somewhat square.

Misc
The smallest passage needs to be 20px or bigger for an army to be able to go through.

Don't make too much terrain. And don't pile terrain above each others. You can only place cities on plains (space without terrain) so more terrain means less cities.(dwarf and elf cities can expand into terrain though)

The default size of a world is 5000x5000px, so your map will most of the time be looped twice (2x2). And a default (2x2) map should be able to hold at least 50 players.

Walls
Walls might get bugged if they are placed on uneven terrain, so if you have walls (Zetamaina) in mind there should be horizontal or vertical terrain on both sides:
